He obviously made the website to get Beatles fans to go there and send him hate mail so he can post it on his site. Reading the site and sending him mail would be a waste of time because he clearly enjoys it.

I wonder how many hit singles he wrote...And how many people are sleeping in front of his house every nightAnd how many lives he changed in his life.And how many of his songs were covered by Elvis Presley, Frank Sinatra, Michael Jackson and the Rolling Stones.And how many of his albums ended up in Rolling Stone's all-time album top 200.

To make a long story short: jealousy. I wonder what this guy has done in his life (in real life that is, not from behind the computer).
